Pathogens target plant TOPLESS and TOPLESS-RELATED (TPL/TPR) proteins, essential for gene expression control, to manipulate plant immunity and facilitate host invasion. This review highlights recent findings on these pathogen interactions.
Area of Science:
- Molecular Biology
- Plant Science
- Genetics
Background:
- Transcriptional corepressors, including TOPLESS and TOPLESS-RELATED (TPL/TPR) proteins, are crucial for eukaryotic gene expression.
- TPL/TPR proteins regulate diverse plant growth, development, and stress responses, acting as signaling hubs.
- Emerging evidence implicates TPL/TPR proteins in plant immunity modulation.
Purpose of the Study:
- To review recent findings on how pathogens target plant TPL/TPR proteins.
- To summarize the mechanisms by which pathogens manipulate plant signaling pathways via TPL/TPR proteins.
- To elucidate the role of TPL/TPR proteins in plant-pathogen interactions.
Main Methods:
- Literature review of recent studies on TPL/TPR proteins and plant immunity.
- Analysis of research on pathogen effectors targeting TPL/TPR proteins.
- Synthesis of findings on TPL/TPR protein function in plant defense signaling.
Main Results:
- Pathogens from diverse groups target plant TPL/TPR proteins.
- Targeting TPL/TPR proteins allows pathogens to subvert plant signaling pathways.
- This manipulation aids pathogens in successful host invasion and disease development.
Conclusions:
- Plant TPL/TPR proteins are critical targets for pathogen virulence strategies.
- Understanding these interactions is key to developing novel plant disease resistance mechanisms.
- TPL/TPR proteins represent a significant nexus of plant immunity and pathogen manipulation.

Transgenic Plants
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
